THING TO DO

Tour the Front-line of the Cold War at Delta-01

Learn what it was like to have the awesome responsibility of thermonuclear war at your fingertips. The thirty-minute ranger guided tour of the control center at Delta-01 begins with a walk through of the grounds and topside support building. Visitors then descend via elevator 31 feet underground to the Launch Control Center to see the electronic consoles used by missileers to control ten Minuteman II missiles.

Built for nuclear war, the control center features a small elevator and a tight underground space. To protect the historic facilities and to provide for visitor safety, each tour is limited to six participants. Advanced reservations are required for all tours.

Visitors and a park volunteer discuss the blast door before entering the launch control center.

The elevator car at Delta-01 is only three feet by five feet wide - six visitors and a ranger are often a tight fit.

Why are tour sizes so small?

The Delta One facility is open to the public only through guided tours, in keeping with the level of security maintained by the U.S. Air Force historically. Given the historic military mission of the Delta-01 facility, the space limited underground control center and limited elevator access are integral to the building. The maximum tour size of six persons per tour plus park ranger escort is established to in order to provide personal interpretation of the park’s primary resources to visitors, to increase visitor safety, and to provide maximum protection for park resources.

What To Do If You Can't Get A Tour

In the summer season especially, demand for tours at Delta-01 exceeds capacity. In addition to visiting the visitor center and Delta-09, a visit to Rapid City's South Dakota Air and Space Museum at Ellsworth Air Force Base offers a number of complimentary features that further explore the Minuteman Missile story. The museum's exhibits include a launch control simulator identical to the control center at Delta-01 and their airpark display includes a Minuteman II missile. During the summer season the base tour includes an opportunity to go inside a missile silo trainer preserved on base.
